Missing Essentials.

[Solvolne]

There are a couple essential songs I think this game is missing.

Danzig - Mother
Dio - Holy Diver
Dio - Rainbow in the Dark
The Darkness - I Believe in a Thing Called Love(Oh so much fun for us who love to play vocals)


Some non-essentials but I think they could be fun anyways.

NiN - March of the Pigs.
A Perfect Circle - Pet
A Perfect Circle - Weak and Powerless
NiN - The Beginning of the End
NiN - Only

Some very unlikely but still I'm hopeful for ones.

Porcupine Tree - Strip the Soul
Porcupine Tree - Sound of Muzak
Porcupine Tree - Trains
Blackfield - End of the World

All and All I think any songs from these artist's would be neat, but these would be my top hopes, and I think would work well with the game play.

Haha I am sure I missed some essentials but those are the top 4 that come to my head.
